NHTED s gar GRAIN-DOOR REMOVER.

To all whom it may concern;

Be it known that we, WILLIAM Issrrr and CLIFFORD M. BROWN, citizens ofthe United States, residing at Enterprise, in the county of Dickinsonand State of Kansas, have in vented certain new and useful Improvementsin Grain-Door Removers, of which the following is a specification.

Our invention relates to new and useful devices for removing grain doorsfrom box cars loaded with grain, and one object is to provide a simple,inexpensive and efficient device of this character whereby one man canreadily remove such grain doors without damage thereto, so that they maybe used repeatedly.

In the usual practice grain doors are generally destroyed in effectingtheir removal due to the fact that the grain in the car exerts suchpressure on said grain doors that the lower door is usually chopped outwith an axe to relieve such pressure. This not only results in loss oftime of the operator and the expense entailed in replacing the destroyeddoors with others, but the chips chopped from the door become mixed withthe grain as it runs from the car and often cause trouble at theelevator where the grain is stored.

By the use of our device the above-mentioned objections are overcome aswill here inafter appear, reference being had to the accompanyingdrawing, in which:

Fig. 1 is a fragmentary perspective view of a car with our device inposition for removing the grain door.

Fig. 2 is an enlarged, broken horizontal section on line II-II of Fig.1.

Fig. 3 i a front elevation of the device.

Fig. 4 is a side elevation of the device.

Fig. 5 is a detail of a pinch bar used in connection with the device.

Referring now in detail to the various parts disclosed by the drawing, Adesignates a box car having the usual sliding door B at each side.

C designates the grain doors which are.

nary construction and constitute no part of our invention whichvwill nowbe described in detail. a Y

2 designates a stand whichis of suf ficient length to reach from the carfioor F to asuitable distance aboveithe topmost grain door C. Said stand2 consists'of a pair of standards 4 spaced a slight distance apart andunited at their upper and'lower ends by a transverse member-(Stand abase 8, respectively. The standards 4 consist, preferably, of angle ironin order to obtain the requisite strength and lightness. The base 8 alsoconsists, preferably, of angle iron, while the transverse member 6 maybe a flat bar.

Each standard 4 has a vertical row of holes 10 the holes in one standardbeing opposite the holes in the companion standard to receive a pin orbolt 12 which constitutes a fulcrum for the pinch-bar 14.

In practice the operator'opens the door B at the side of the car fromwhich the grain is to be removed. The stand 2 is then so positioned thatits base 8 will rest upon the car floor F while one of the standards 4will bear against the adjacent door post D where it is held by thetransverse member 6, one end of which bears against the rear surface ofsaid door post I), as shown .best by Fig. 2. The pin or bolt 12 is thenpositioned in two of the opposed holes in the standards 4 to comeapproximately on a line with the lower edge of the uppermost grain doorC and constitute a fulcrum for the pinch bar 14, the pointed end 16 ofwhich is forced beneath the lower edge of said uppermost grain door C.The handle end of the pinch bar 14 is then forced down wardly to causesaid pinch bar 14 to rock upon its fulcrum 12 and raises the adjacentend of the grain door C as disclosed by Fig. 1. A portion of the grainrunsout through the opening thus provided and thereby relieves the graindoor 0 of considerable pressure, so that its opposite end can be easilyraised withour device as above-described. After the upper grain door Chas been removed the stand 2 is taken away, as the lower grain door Ccan be readily removed with the pinch bar 14 by using the car floor F asa fulcrum upon which said pinchbar 14 is rocked.

The entire operation of removing the grain doors G and O occupies butlittle time and is accomplished without damage so that they may be usedrepeatedly and thus avoid the expense of providing new grain doors foreach car as it is loaded with grain.

From the foregoing description it is apparent that we have provided agrain door remover embodying the advantages above pointed out, and whilewe have shown and described the preferred construction, combination andarrangement of parts, we re serve the right to make such changes asproperly fall within the spirit and scope of the appended claim.

Having thus described our invention, what we claim and desire to secureby Letters Patent, is:

A device of the character described consisting of a pair of standards ofsufficient length to extend from the threshold of a car-doorway to apoint above a grain door weasel partially closing said doorway; a baseuniting the lower ends of said standards, a transverse bar uniting theupper portions of the standards and extending laterally from each sideof the same to engage either doorjarnb, a fulcrum adjustable todifferent elevations on the standards, and a lever associated with saidfulcrum and having a reduced end for insertion beneath the differentsections of the grain door to lift said sections vertically when theopposite end of said lever is forced downwardly.

In testimony whereof we aflix our signatures, in the presence of twowitnesses.
